c#UDP协议

UDP协议是不可靠的协议,传输速率快

服务器端:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; using System.Net.Sockets;
using System.Net;
using System.Threading; namespace UDPServer
{
class Server
{
private Socket _ServerSocket; //服务器监听套接字
private bool _IsListionContect; //是否在监听 public Server()
{
//定义网络终节点(封装IP和端口)
IPEndPoint endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"),);
//实例化套接字
_ServerSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
//服务端绑定地址
_ServerSocket.Bind(endPoint); EndPoint ep = (EndPoint)endPoint; while (true)
{
//准备一个数据缓存
byte[] msyArray = new byte[ * ];
//接受客户端发来的请求,返回真实的数据长度
int TrueClientMsgLenth = _ServerSocket.ReceiveFrom(msyArray,ref ep);
//byte数组转字符串
string strMsg = Encoding.UTF8.GetString(msyArray, , TrueClientMsgLenth);
//显示客户端数据
Console.WriteLine("客户端数据:" + strMsg);
}
} static void Main(string[] args)
{
Server obj = new Server();
}
}
}

客户端:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks; using System.Threading;
using System.Net;
using System.Net.Sockets; namespace UDPClient
{
class Client
{
private Socket _ClientSocket; //客户端通讯套接字
private IPEndPoint SeverEndPoint; //连接到服务器端IP和端口 public Client()
{
//服务器通信地址
SeverEndPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), );
//建立客户端Socket
_ClientSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); EndPoint ep =(EndPoint) SeverEndPoint; while (true)
{
//输入信息
string strMsg = Console.ReadLine();
//退出
if (strMsg == "exit")
{
break;
}
//字节转换
Byte[] byeArray = Encoding.UTF8.GetBytes(strMsg);
//发送数据
_ClientSocket.SendTo(byeArray,ep);
Console.WriteLine("我:" + strMsg);
}
//关闭连接
_ClientSocket.Shutdown(SocketShutdown.Both);
//清理连接资源
_ClientSocket.Close();
} static void Main(string[] args)
{
Client obj = new Client();
}
}
}
